What Is Design For Testability In Software Testing?

In software design for testability is the degree to which a software artifact, a software system, software module, requirements- or design document) supports testing in a given test context. If the testability of the software artifact is high, then finding faults in the system (if it has any) by means of checking out is easier.<br>

  1. Design for Testability Towards Industry 4.0 & IoT intelligent software, pleasant work www.vayoinfo.com

  2. Change from NPI Past Yesterday Today Vayo customer solved this issue. They may still happen at your side. Above issues puzzles most of us. Ex.: Intel/Venture/SurfaceArt/Bosch… Intelligent Vayo NPI software makes manufacturing more agile and smart!

  3. Are you always willing to stay with those issues? Quality defects, reliability issue, process headache, business risk Design Equipment programming 1 4 • Wrong polarity, location offset, inline fine- tune, … • Lower test coverage, lower utilization, … No thermal consideration, small annual ring small, silkscreen error, Silkscreen incomplete, … >30% PCB design comes with problem. • • Manufacturing NPI cycle 2 5 • Frequent prototyping, high cost • Long cycle, impact time to market, … Short, open, tombstone, cold sold, Void, … >60% defects could be found prior to build • • 3 6 Post sales Process design sold joint crack, sold joint peeloff, … Repair rate for consumer product: 5%~37% in initials 3 years • Difficult to transfer knowledge • No effective tool to continually improve process capability • … • • IPC research: 80% defects could be found and resolve during NPI stage.
